Title:
COLLISION AVOIDANCE IN A WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/084022
Kind Code:
A1
Abstract:
Apparatuses, methods, and systems are disclosed for collision avoidance. One apparatus includes a processor that detects energy in a detection slot within a first time period over a first frequency resource of a transmission resource unit ("TRU"). The TRU includes the first time period, a second time period contiguous in time with the first time period, a second frequency resource, and a third frequency resource contiguous in frequency with the second frequency resource. The energy is below a predetermined threshold. The apparatus also includes a transmitter that transmits a time-contiguous signal after the detection slot until an end of the first time period over the first frequency resource. The transmitter transmits data within the second time period over the third frequency resource. The transmitter transmits a scheduling assignment ("SA") within the second time period over the second frequency resource. The SA includes information related to the data.
